EQUIPMENT

Duncan & Grove is a playground equipment design, manufacture, and installation company with over 9 years experience building award-winning playgrounds. We manufacture a range of high-quality natural play equipment as well as building large bespoke playgrounds. Our products are hand crafted out of European hardwood that doesn’t require chemical treatment so they are durable and kind to the environment.

We have over 200 products in our catalogue range. We make all of our own playground equipment at our West Sussex factory so we can adapt our existing products to suit your needs or we can design and build something entirely new. Flexibility and adaptability are at the heart of our business, our objective is to design what you want and build it in a way that will last. Our product range is based around natural playground equipment and is separated into two different styles; oak playground equipment and robinia playground equipment.

OAK

PLAYGROUND

EQUIPMENT

Our oak range is made from large section sawn oak beams. These are more geometrical in appearance than our robinia playground equipment however the nature of the oak with the grain of the wood and size of the beams creates a tactile organic feel. We design and build all of our oak playground equipment at our workshop in West Sussex meaning we can adjust our designs to your needs. Within our range we have climbing frames, climbing nets, hammocks, play huts, swings, trim trails and more. If you don’t see something you are after in our range let us know and we can design and build it for you.

OAK

Oak is a naturally durable European hardwood with a life span between 15 and 25 years in ground contact. We use high-quality QPA structural oak beams to manufacture our oak range. We offer a 15 year warranty against oak in ground contact and a 20 year warranty for oak out of ground contact.

  • Each beam is checked for ring shake, knots, wood worm, rot and excessive sapwood. Any beam that fails to meet our exacting standards is rejected. The beams are sanded smooth.
  • Larger section oak beams contain the boxed-heart of the wood and so there is a chance they may split to some extent. To reduce the extent of splitting, we cross bolt all of the ends of our poles with stainless steel bolts.
  • We treat our oak play equipment with a high-quality uv protective oil to reduce the affect of graying and checking on the timber.
  • We use heavy duty stainless steel fixings.
  • Where possible we use traditional oak framing construction techniques.

ROBINIA

PLAYGROUND

EQUIPMENT

Our robinia range retains the natural form of the tree with natural twists and curves, creating structures that has an intrinsically organic feel. We only use the highest-quality robinia for the manufacture of our products. As robinia is naturally very durable so our robinia playground equipment does not require any chemical treatment.

ROBINIA

We use the highest-quality robinia to manufacture of our products. The robinia used in our play equipment goes through a rigorous five step pre-treatment process to ensure it’s quality. We offer a 15 years guarantee for robinia in ground contact and a 20 year guarantee for robinia out of ground contact.

  • Step 1 – Debarked and sanded smooth. Bark and sapwood are not durable and rot quickly so after the trees are felled they are debarked and the sapwood removed before being sanded smooth.
  • Step 2 – Rest the timber. We keep the timber at our yard allowing it to rest and air dry before use. The natural drying process lets us filter out timbers that have formed large cracks or splits during the resting period.
  • Step 3 – Knot removal. We carefully inspect each pole with only the highest quality poles being accepted. Knots are assessed to determine if they are sound. Too large and the timber is rejected. Small knots are removed, the timber treated and the knot plugged with hardwood timber dowel.
  • Step 4 – Cross Bolting. Robinia poles contain the boxed-heart of the wood and can split. The worst are selected out during the resting period but to reduce the risk further we cross bolt the ends with stainless steel bolts.
  • Step 5 – UV Protective Oil. We apply a coat of high-quality uv protective oil to our robinia poles to reduce the affects of graying, cracking and protect the timber.

QUALITY

MATERIALS

Quality and durability are a central part of anything we design and build. We have considerable experience making wooden outdoor structures and know through that experience which materials stand the test of time, ensuring that all of our play equipment is easy to maintain and lasts a long time.

playground equipment hardwood properties

HARDWOOD

TIMBER

At Duncan & Groves we only use naturally durable oak and robinia hardwoods from FSC certified sawmills. These timber species are both physically hard and naturally durable.

Robinia is grown in commercial quantities in Europe. The trees are generally coppiced providing smaller fast grown sections. This limits the diameter and length of timber available but means it is ideal for provding fast growing sustainable hardwood for playgrounds.

Robinia is classed as highly durable with a life span in excess of 25 years in ground contact without chemical treatment. Oak is classed as durable with a life span between 15 and 25 years in ground contact without chemical treatment.

Timber is made up of 3 major layers; bark, sapwood and heartwood.

  • The bark and sapwood are full of sugary starches and sap which attracts pests and forms rot. It is essential to remove these layers to help with the longevity of the equipment.
  • The Heartwood is the only part we use for manufacturing. It has the highest quality properties, is durable, robust and does not require any treatment.

ROPES &

NETS

We manufacture our nets in house. This allows us to adapt our designs quickly and easily to design changes, take accurate measurements before the net is made, and easily alter the net if required. We have mobile site presses so we can attend site at short notice to conduct any maintenance required ensuring your playground is fit for purpose and remains in use.

Our nets are made using high-quality:

  • Wire reinforced polypropylene rope
  • Aluminium ferrules
  • Stainless steel chain
  • Stainless steel chain connectors

STEEL

COMPONENTS

Our steel components are manufactured from quality stainless steel and are available in either a brushed or polished finish. All of our stainless steel comes with a 30 year guarantee although the expected service life is much greater than this.

STEEL

FOOTINGS

We recommend the use of steel footings when installing timber playground equipment. The main factor determining the life span of wooden play equipment is the wooden uprights rotting at the point where they meet the ground. Although oak and robinia are naturally durable by using steel footings and lifting the timber out of ground contact you can significantly increase the longevity of the playground equipment. We offer 20 year guarantees on robinia and oak uprights on steel footings.

  • Hollow Section Steel Footings – Where the post is being supported entirely by the steel footing and is not part of a larger supporting structure, we use hollow section steel where the timber is inserted inside of the shoe. This allows a much larger lateral load to be placed on the post than would otherwise be the case.
  • Flitch Plate Steel Footings – Where the post is part of a larger structure that is self supporting and so just needs elevating from ground level with the steel footing we use a flitch plate design.
  • Mild or Stainless Steel – We offer steel footings in either mild steel that is hot dip galvanised or stainless steel. Stainless steel is superior in terms of aesthetics and longevity but is more expensive.
